Re: [SLUG] Meaning of Nonsense in s p a m

I am not sure about the garbage that appears in subjects and in the middile of some spams but I am fairly sure the html tags in the middle of words are an attempt to obfuscate the true content of the spam from simple text filtering spam filters.  The other stuff is probably the same.

I think spamassassin attempts to look past this.
